Remember that we were never able to see someone's health - just that 'she/he looks strong' and 'she/he looks weak' - but now we can see their health bars (Down with bars! - but see the other topic for that...)
Well - why not bring it back? But in a different form? - now that skills are a part of the game - a good addition I think...
Strength - as in muscular build etc - i'e: comabt skill, or ability to dig etc... is something you can see - just think about when you look at RL people - you can get some idea of how strong they are...
Other skills might also be visable, but strength, or some similar skill, is one that would be fairly obvious...
